Problems solved by technology

In order to meet this requirement, a method of increasing the concentration of the color material in the color filter can be mentioned, but once the concentration of the color material is increased, the deterioration of the performance of the colored photosensitive resin composition such as the deterioration of the pattern shape will occur, so it is not preferable.
In addition, in order to have the target color characteristics, the color filter needs to be made into a thick film, but when it is applied to a liquid crystal display device, it will cause light color mixing with adjacent pixels, so thickening the film is also not preferable.

preparation example Construction

[0054] The preparation method of the pigment dispersion liquid is not particularly limited, and the pigment dispersion liquid of C.I. Pigment Green 58, C.I. Pigment Yellow 138, and C.I. 185 pigment dispersion and C.I. Pigment Yellow 138 pigment dispersion can also be prepared by (ii) mixing C.I. Pigment Green 58, C.I. Pigment Yellow 185 and C.I. Pigment dispersion of C.I. Pigment Yellow 185 and C.I. Pigment Yellow 138.

[0055] In addition, as the colorant (A), in addition to the above-mentioned C.I. Pigment Green 58, C.I. Pigment Yellow 185, and C.I. Pigment Yellow 138, known pigments and dyes can also be used. In the present invention, the total amount of C.I. Pigment Green 58, C.I. Pigment Yellow 185, and C.I. Pigment Yellow 138 in 100% by mass of the colorant (A) is preferably 50% by mass or more, more preferably 60% by mass or more, and furthermore It is preferably 70% by mass or more, particularly preferably 80% by mass or more, still more preferably 90% by mass or more...

Embodiment

[0303] Hereinafter, the present invention will be described more specifically with reference to the examples. The present invention is not limited by the following examples. It can be implemented with appropriate changes within the scope of the spirit described in the context. These are all included in the technology of the present invention. within range. In addition, below, unless otherwise specified, "part" means "mass part", and "%" means "mass %".

Synthetic example 1

[0305] Into a 1L flask equipped with a reflux cooler, a dropping funnel, and a stirrer, an appropriate amount of nitrogen gas was introduced to form a nitrogen atmosphere, and 280 parts by mass of propylene glycol monomethyl ether acetate was added, stirred and heated to 80°C. Next, 38 parts by mass of acrylic acid, 3,4-epoxytricyclic [5.2.1.0 2,6 ] A mixed solution of 289 parts by mass of a decan-8-yl and / or 9-yl ester mixture and 125 parts by mass of propylene glycol monomethyl ether acetate was dropped over 5 hours. On the other hand, a mixed solution obtained by dissolving 33 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) in 235 parts by mass of propylene glycol monomethyl ether acetate was dropped over 6 hours. After the dropwise addition, the same temperature was maintained for 4 hours, and then cooled to room temperature to obtain a copolymer having a type B viscosity (23° C.) of 125 mPa·s, a solid content of 37.0% by weight, and a solution acid value of 27 mg-...

Abstract

The subject of the invention is to provide a colored photosensitive resin composition which has excellent solubleness in developing solution and can be used to prepare specific patterns, can provide highly precise colored filters with thin films. The invention relates to the colored photosensitive resin composition comprising a colorant(A), a resin(B), a polymerizable compound(C), a polymerization initiator(D). The colorant(A) contains at least one kind selected from the group consisting of C. I. pigment green 58, C.I. pigment yellow 185 and C.I. pigment yellow 138.

Description

technical field [0001] The present invention relates to a green colored photosensitive resin composition, and particularly relates to a colored photosensitive resin composition containing C.I. Pigment Green 58, C.I. Pigment Yellow 185, and C.I. Pigment Yellow 138 as a colorant (A). Background technique [0002] In recent years, the development of display screens to expand the displayable color gamut has been advancing, and color filters, which are part of it, are also required to have deeper colors. In order to meet this requirement, there is a method of increasing the concentration of the color material in the color filter. However, if the concentration of the color material is increased, the deterioration of the performance of the colored photosensitive resin composition, such as the deterioration of the pattern shape, is not preferable. In addition, in order to obtain the target color characteristics, the color filter needs to be made into a thick film. However, when it i...
